[Q] battery overheating question

hey all, maybe its just my paranoid self, but i just want to be sure;
i was charging my phone, and at the same time, i was playing slice it. suddenly i realized that the back of the phone was getting really hot, and i checked the temperature. it was about 45c, and i was gettin freaked out, so i took the batttery and put in the fridge for like 10 seconds, before realizing that was a stupid mistake. after about 5 minutes, it cooled back down to 30.5c. i believe that perhaps the battery was around 45c for about a minute or so.
I was just wondering, do you think my battery life will suffer from my idiotic antics? Im a bit worried that itll have a significant impact, even if it was for a few minutes? Did i 'burn' out some of the lithium ion cells?
much help appreciated!
thanks alot!

Just curious, does only your battery get warm, or does the top half of the phone (above the battery) got hot too?

Phone only overheated when I had bluetooth and wifi running while charging

its just the back of the phone where the battery is located

Mine did the exact same thing last night with fruit ninja of all things. I also put my whole phone in the fridge for one minute and it dropped the battery temp from 45c to 38c. The battery condition also said "overheated" instead of "good" which it has said since then.

nice to know that im not the only one :]

Can anyone answer my question about if the short amount of overheating damaged my battery?

Mine got to 53c while doing absolutely nothing, any idea what causes this?

I don't think anyone really knows and begging for an answer is a quick way to get flamed.
I know that if you were to rapidly cool metal or another material in that same manner, it would crack. I don't know if that same issue would apply to batteries. I definitely wouldn't put anything overheated directly into a frozen environment like that.

+1 not a great idea, just take battery out and let it sit

Mine had the same problem. Whenever i put it on charge it would heat up within minutes and then upon unplugging it would cool down. I read somewhere in the forum to discharge completely and then recharge to full. I did that and its been 1 week since that and no problems with overheating and battery life is also improved. My battery`s health is still GOOD i checked using * # * # 4 6 3 6 # * # *
Hope this helps.

I undervolted the cpu. Overheating almoat stopped. I swapped battery and has been better since. Usually running two quadrants i would start feeling it get hotter and hotter. On new battery i run four an don't notice any major change.
G2x with CM7 and trinity kernel

out of the blue overheating
My phone was awesome...but now it overheats....??
I am going to try and undervolt and see if that helps my problems but my phone just goes crazy hot when it's asleep and idk what to do, even w/ a new warranty phone, and i could tell it's new cause it still had the green tap by the buttons and stuff...the old one got crazy hot, but only after cm7 build33....and this was also after i changed the recovery to 3101 ext4 supported one....can a recovery affect your roms (overheat it) i would't think so, it only loads on command idk how it would....hmmmmm my vibrant would be a dead cold 28-29c when on idle/sleep but w/ this phone it just gets hot and is about 37-43 when doing nothing.....i'm going to try the undervolt thing w/ cm7 latest build and faux123's kernel 0.1.1 and try to undervolt it, i'll search thru that thread for good undervolting starting points...and play w/ that......idk i'm just confused why it is just now happening and not before, i had it on launch day and no problems till last week....i'm lost..

Infuse battery extremely hot???

I've been using it for ten minutes on the charger and for some reason the screen brigntness was low. So I went to the settings and it says "to avoid overheating maximum brightness has been reduced".. and my temperature is 47 degrees now. Anyone elses phone getting hot?

This used to happen with my Samsung Vibrant 4g... i believe you could burn the phone if it continues, it might be a factory issue.

Same here, charging on the wall charger with screen off, it hit 47c and won't go to max brightness.

I've also jist noticed after 50% the charging time decreases significantly. I went from 50% to 90% in 45 min

Mine got hot and I lost all service. It was up to about 93% charge and it just lost all cellular service. I had it rooted but didnt carrier unlock it. Got a replacement phone this morning and Im leaving it alone to see how it does while charging. With the long charge times this could be an issue. Not everyone can let a device set and not mess with it for 3-4 hours, lol I know I cant.

Technically I don't think you are supposed to be using your phone while on the charger... This happens to all phones just some heat up faster than others.... My old ATT Startac did that, SE W900, Captivate, and this one.
It really kills the life of the battery too as well. Nature of the beast....

Had to get a new one but so far so good, 95 degrees F while charging.
Sent from my SAMSUNG-SGH-I997 using XDA App

Just an update, charged past 50% on the new phone and its picking up speed and charging much faster. Temp is steady at 87F. Seems like I really just had a bad unit because the other phone got up to 116F just charging with the screen off.

[Q] How hot is too hot?

Yesterday my G2X was really hot it was over 110 because of the weather... So how hot is too hot and what to do to protect the phone when you have to be in sun? Any advice?

I have same problem. Its 110 in Vegas and there is not much you can do.
G2x with CM7 and faux kernel. NONSENSE!!!!

I was at a outside event and my phone was at 119°F.
Sent from my LG-P999 using XDA Premium App

Mine was at 120f sitting on my desk at work. Considering a swap.

My phone gets hot sitting in my truck dash mount streaming music, then again I live in Florida. On a side note it doesn't get hot at all playing drag racing for 4 hours straight.

Here is what LG says:
Humm... Max Storage temp is about 122F, so I'd be careful about leaving it in a hot car during the summer, especially in direct sunlight. The Operating Temp is about 113F ...
There is Thermal protection built into the phone so if the heat gets excesive, it should shut off, But personally I wouldn't push it to that extreme. I use a little app called "Battery Indicator Pro" that makes it easy to see what the reported temperature of the phone is.
If the phone is uncomfortable to hold, then it's too warm... Remember, Heat is NOT a friend to Electronics of any type.
If your phone is getting too hat to hold, I'd contact T-Mobile or LG Support about getting it repaired / replaced. LG can be reached at (800) 793-8896.

I noticed mine was warm (about 40c) when using my data and just surfing. When it went up to 45c, I turned the data off immediately. I let it sit for a little bit and it went back down to the 20s.
It was the first time it got that warm so I'll chalk it up to the weather.

I had mine in my car while I was driving around running some errands 2 days ago. It was 101 degrees outside, and the phone shut off...when I turned it back on, it said it was 125 degrees...I"m guessing that was too hot. I haven't noticed any indications of permanent damage, so I guess the safety feature worked.

I hit 122°F today and phone lock up. Keep phone out if heat. LOL

101 in KS?? And I thought TN was bad.

Overheating with LED cycling colors

Heya,
Last night I was playing Angry Birds in bed while plugged in a Kidigi dock. All is well. Now let me define some preconditions first.
The phone does get hot while:
1. Charging
2. Screen is on for a long time
3. Heavy CPU load
4. That goddamn hot weather isn't helping either
Right?
Put above conditions together. Temperature is 48.3C. I never thought I'd need to use a cooling fan on a phone, honestly. I did that to an overheating AMD desktop some time ago...
The thing is I knew there was something going on not by feeling the hot phone (remember the dock part?) but by seeing the LED strangely cycling through all three colors. Anyway I shutdown everything running, turned off the screen and kept my fingers crossed. The flashing stopped almost immediately as it dropped one degree in an instant. Took it 15 minutes to cool down to the normal 38C.
I looked around and didn't find a definitive answer for this one, even on HTC's site where they supposedly list notification color meanings. Therefore I now define a new one, let's call it "I'm just about to blow up now, k10xbye".
Has anyone else had such a drastic overheating case with this type of notification?

Nope. My phone hit 52 degrees. Nothing happened to it. Just turned the screen off and it cooled down

What was the third color? Mine only flashes orange for when its dying, solid for when its charging. Flashes green for notification, solid green when its fully charged.

Charging is orange.

I monitor my battery temperature by dialing *#*#4636#*#* which takes you into a section called testing, and then selecting battery information. This displays temperature along with other info. At one time, it actually said overheating. it has not happened again but if it does, I will seek a replacement unit. There is no way that any of this, your sceneraio or mine, is normal.

It's not normal. Heavier games with 3D don't do that. Max temp achieved was 42.

My EVO4G used to do that when I had it in the tank bag on my motorcycle listening to Pandora. The plastic cover would cause it to heat up and the led would cycle and it would stop charging and shut down.
There is a reason to this. The battery is mainly lithium. Lithium is highly reactive (read lots of very hot flames and sparks and excitement that you probably don't want going off near your girlfriend or dog or sensitive government documents). They use the same type batteries in RC aircraft, only lots bigger, and youtube will show some pretty spectacular lithium battery explosions, if you care to search them.
Imagine that going off in your pocket.
Ouch, a little....

Heh shutting down is reasonable, heating up till shutdown during normal use is not. And yes I watched those videos on YouTube when I got my wrist charger.

I m also suffering... But only gets hotter when u use the phone while charging, or use the phone for almost 20 mins continuously...

Here you go. 20 minutes Angry Birds, no charging, 43 degrees. Decided to quit. Anyway I've had enough for today plus not so pleasant on the hands.

132 Degrees?

Wow this is a new high. I was talking on the phone with headphones in, set it down on the table, started playing words with friends and hanging with friends simultaneously over 4g, and I noticed that the SCREEN felt hot. At this point I started to download a thermometer app. After playing another round of hanging, my headphones made beeping noises and the phone went from 5 bars 4g to no service. So I checked my thermometer app and it said 55 Celsius, which I then googled to be 132 Fahrenheit!!
Is this dangerous for the internals? I think the software killed the radio because of this. I put the phone in the freezer for 30 seconds and it came out at 50 degrees and the radio worked fine again.

Yes. While the system internals may be able to handle this temperature (although it's probably close to max), it's pretty dangerous to the battery and can ruin it.

Yeah i think my battery is draining significantly faster today. Could that have caused it?

if it does this frequently its usually the sign of a defective or dying battery or possibly bad phone... they should be able to give you a new battery or set you up with a replacement no problem, I think its a common issue from what I've heard in the VZ stores near me
blazing through on my 4G Droid Charge

I ordered this from tiger direct and i can't really go two Weeks without my phone so no giving it back. Also this phone works perfectly besides this one incident and the GPS, so i would rather not get a replacement that has data dropping, for example
